Description/Abstract

A sensor network is described which obtains datafrom nodes on and inside glaciers. Power management throughscheduling and selective control is used to allow a lifetime of atleast one year on batteries. Radio links in the glacier and across2.5km distances are used for data and commands. The prototypesystem was installed in Norway in 2003 and this paper describesdetails of the full design for 2004 through discussion of thelessons learnt.
